Etiology and Multi-Drug Resistant Profile of Bacterial Infections in Severe Burn Patients, Romania 2018-2022.

Infections in severe burns and their etiology are and will remain a big concern for the medical field. The multi-drug resistant strains of bacteria are a challenge of today's medicine. The aim of our study was to identify the etiological spectrum of bacterial infections in severe burn patients in Romania and their multi-drug resistant patterns. We performed a prospective study that included 202 adult patients admitted to the intensive care unit (ICU) of the Clinical Emergency Hospital of Plastic, Reconstructive Surgery and Burns, Bucharest, Romania (CEHPRSB), from 1 October 2018 to 1 April 2022, a period which includes the first 2 years of the outbreak of COVID-19. From each patient, wound swabs, endotracheal aspirates, blood for blood culture, and urine were collected. The most frequently isolated bacterium was Pseudomonas aeruginosa (39%), followed by Staphylococcus aureus (12%), Klebsiella spp. (11%), and Acinetobacter baumannii (9%). More than 90% of Pseudomonas aeruginosa and Acinetobacter baumannii were MDR, regardless of the clinical specimen from which they were isolated.

Polyphenols and Cardiometabolic Health: Knowledge and Concern among Romanian People.

The cardiometabolic health of the population is a crucial indicator of public health, considering the significant impact of cardiovascular disease (CVD) and diabetes on global mortality. Determining the population's knowledge and the predictors of these pathologies is essential in developing effective educational and clinical strategies for the prevention and management of cardiometabolic risk (CMR). Polyphenols are natural compounds with a multitude of beneficial effects on cardiometabolic health. This study explored the current knowledge, understanding, and awareness of CMR, the benefits of polyphenols among Romanians, and how sociodemographic and clinical characteristics influence this aspect. Five hundred forty-six subjects responded anonymously to an online questionnaire designed to assess their knowledge. The data were collected and analyzed based on gender, age, education level, and BMI status. Most respondents expressed concern to a great or very great extent about their health (78%) and food (60%), with significant differences (p < 0.05) depending on age, educational level, and BMI status. Of the respondents, 64.8% declared that they were familiar with the CMR term. Still, the results showed a weak correlation between the stated risk factors and the self-assessment of increased risk (r = 0.027) for CVD or diabetes. Only 35% of the respondents reported a good or very good knowledge of the term "polyphenols", 86% recognized the antioxidant effect, and significantly fewer (26%) recognized the prebiotic effect. Developing and implementing targeted educational strategies to enhance learning and individual behaviors related to CMR factors and the benefits of polyphenols is necessary.

Bioactive Potential of Elderberry (Sambucus nigra L.): Antioxidant, Antimicrobial Activity, Bioaccessibility and Prebiotic Potential.

Due to its abundance of physiologically active ingredients, one of the oldest medicinal herbs, elderberry (EB) Sambucus nigra L., is beneficial for both therapeutic and dietary purposes. This study determined the bioaccessibility of the phenolic compounds and the prebiotic potential of the polyphenols from freeze-dried EB powder (FDEBP), along with the antioxidant and antimicrobial activities of this extract. The most significant phenolic compounds in black EB are represented by anthocyanins (41.8%), predominating cyanidin-sambubiosides and cyanidin-glucosides (90.1% of the identified anthocyanins). The FRAP assay obtained the highest antioxidant activity value (185 ± 0.18 µmol Fe2+/g DW). The most sensitive to the antimicrobial activity of the extract was proven to be Staphylococcus aureus, and Pseudomonas aeruginosa had the lowest minimum inhibitory concentration of 1.95 mg/mL. To determine the prebiotic potential of the polyphenols, the cell growth of five probiotic strains (Lactobacillus plantarum, L. casei, L. rhamnosus, L. fermentum and Saccharomyces boulardii) was tested. The influence on cell growth was positive for all five probiotic strains used. Overall, the most significant increase (p < 0.05) was recorded at 1.5% FDEBP, on L. casei with a growth index (GI) of 152.44%, very closely followed by GI at 0.5% and 1% concentrations. The stability of the total phenolic compounds through simulated gastronitestinal digestion was increased (93%), and the bioaccessibility was also elevated (75%).

Prevalence of undiagnosed hepatitis B virus infection in patients with COVID-19A single center retrospective study.

At its onset, the coronavirus disease 2019 (COVID-19) pandemic brought significant challenges to healthcare systems, changing the focus of medical care on acute illness. Disruptions in medical service provision have impacted the field of viral hepatitis, with screening programs paused throughout much of 2020 and 2021. We performed a retrospective study on consecutive outpatients with COVID-19 during the second and third wave of COVID-19 in Romania, from November 2020 to April 2021, aiming to characterize the prevalence of undiagnosed hepatitis B virus (HBV) infection among patients presenting with acute illness. Overall, 522 patients had available records during the study timespan. Their mean ±â€…standard deviation age was 51 ±â€…13 years; 274 (52.5%) were male. We identified 16 (3.1%) cases of active HBV infection; only six of these patients were aware of their HBV status, and 3 of the newly diagnosed cases were identified as candidates for HBV treatment. A total of 96 patients (18.4%) had serological markers suggestive for prior HBV vaccination. A large proportion of patients (n = 120, 23.0%) had positive HBV core antibodies; among these, 90 (17.2%) had cleared a previous HBV infection (being positive for HBV surface antibodies and HBV core antibodies). We identified the following parameters that were significantly more frequent in patients with a history of HBV infection: older age (P < .001), hypoalbuminemia (P = .015), thrombocytopenia (P < .001), thrombocytopenia followed by thrombocytosis (P = .041), increased blood urea nitrogen (P < .001) and increased creatinine (P = .011). In conclusion, the COVID-19 pandemic has taught us essential lessons about the importance of maintaining access to screening programs and of ensuring active monitoring of patients with chronic infections such as hepatitis B, even during a medical crisis.

Experimental research in topical psoriasis therapy (Review).

Psoriasis, one of the most prevalent inflammatory diseases in dermatologic pathology, remains a challenge in regards to the therapeutic approach. Topical therapy for psoriasis is a current trending subject as it implies good compliance for the patient, few adverse systemic reactions and a targeted effect. Numerous substances are now being tested, from natural to synthetic compounds and already known substances in improved formulas such as vesicular systems. The aim of this article was to conduct a literature review regarding the topical therapy of psoriasis in animal models, between June, 27, 2019 and July 9, 2020. For this article, the authors conducted extensive research in PubMed with the following keywords: Psoriasis AND (topical OR local) and (therapy OR treatment) AND (mice OR rats). The main new studied substances included lycopene, sodium butyrate, salvianolic acid B, small interfering RNAs (siRNAs) in ionic liquids, albendazole, phosphodiesterase inhibitors, biomimetic reconstituted high-density lipoprotein nanocarrier gel containing microRNA (miRNA)-210 antisense, thymoquinone in ethosomal vesicle, Sea buckthorn oil (Hippophae rhamnoides), nitidine chloride, Melissa officinalis spp. Altissima extract and [1-(4-chloro-3-nitrobenzenesulfonyl)-1H-indol-3-yl]-methanol (CIM). New formulas of already known anti-psoriasis substances such as: Cyclosporine, methotrexate, calcipotriol, tazarotene, protein kinase p38 and integrin α5ß1 as a target, are also reviewed. Recent research in topical psoriasis underlines the importance of animal experimental research in dermatology, providing a starting point for developing new therapeutic approaches in one of the most frequently diagnosed chronic dermatologic diseases. Vesicular systems are now providing the best vehicle for topical therapy, thus easing the action of the active substances at their target sites.

Surveillance of medically-attended influenza in elderly patients from Romania-data from three consecutive influenza seasons (2015/16, 2016/17, and 2017/18).

BACKGROUND: Influenza is an acute infection affecting all age groups; however, elderly patients are at an increased risk. We aim to describe the clinical characteristics and the circulation of influenza virus types in elderly patients admitted for severe acute respiratory infection (SARI) to a tertiary care hospital in Bucharest, Romania, part of the I-MOVE+ hospital network. METHODS: We conducted an active surveillance study at the National Institute for Infectious Diseases "Prof. Dr Matei Balș," Bucharest, Romania, during three consecutive influenza seasons: 2015/16, 2016/17, and 2017/18. All patients aged 65 and older admitted to our hospital for SARI were tested for influenza by PCR. RESULTS: A total of 349 eligible patients were tested during the study period, and 149 (42.7%) were confirmed with influenza. Most patients, 321 (92.5%) presented at least one underlying condition at the time of hospital admission, the most frequent being cardiovascular disease, 270 (78.3%). The main influenza viral subtype circulating in 2015/16 was A(H1N1)pdm09, followed by A(H3N2) in 2016/17 and B influenza in 2017/18. Case fatality was highest in the 2015/16 season (3.7%), 0% in 2016/17, and 1.0% in 2017/18. Vaccination coverage in elderly patients with SARI from our study population was 22 (6.3%) over the three seasons. CONCLUSIONS: Our study has highlighted a high burden of comorbidities in elderly patients presenting with SARI during winter season in Romania. The influenza vaccine coverage rate needs to be substantially increased in the elderly population, through targeted interventions.

Characteristics of influenza in elderly patients with and without diabetes, hospitalized for severe acute respiratory infection in a tertiary care hospital from Bucharest Romania - a three-year prospective epidemiological surveillance study.

INTRODUCTION: Patients with diabetes may be at a higher risk of developing complicated influenza. We report the characteristics of influenza in hospitalized elderly patients with and without diabetes, in three consecutive influenza seasons. METHODS: The study included patients admitted for severe acute respiratory infection (SARI) in the National Institute for Infectious Diseases "Prof. Dr. Matei Balș", Bucharest, during a three-year active epidemiological surveillance study (2015/16, 2016/17, 2017/18), in the I-MOVE+ hospital network. RESULTS: A total of 349 patients were tested by PCR over the duration of the study. The percentage of patients with diabetes was comparable throughout the seasons: 34.7%, 28.3% and 30.4% (p=0.587). Influenza A was the main viral type circulating in 2015/16 and 2016/17 (100% and 97.6%) in our study population, while in 2017/18, B viruses predominated (90.0%). Diabetics presented a higher median number of comorbidities (3 vs. 2) p<0.001, and two-fold higher odds of also associating obesity (OR=2.1, 95%CI:1.3-3.4, p=0.003), compared to those without diabetes. Diabetics also tested positive for influenza more often (p=0.296). Only 6 patients with diabetes (5.4%) from our study had been vaccinated against influenza, and most (n=4) of those who had been vaccinated tested negative for influenza. CONCLUSIONS: Our study is the first to describe the circulation of influenza viral types in elderly diabetic patients hospitalized for SARI. The results reinforce the national and international recommendation to vaccinate against influenza all patients with diabetes.
